IMPROVEMENT IN CULTIVATORS.

To all whom it may concern:

Be it known that I, CHARLES HOLMAN, of Cameron, in the county of Warrenand State of Illinois, have invented a new and Improved Uultivator; andI do hereby declare that the followingis a full, clear, and exactdescription of the same, reference beinghad to the accompanyingdrawings, making a part of this specification, in which Figure 1 is aside sectional view of my invention, taken in the line x a, Fig. 2; Fig.2, a plan or top view of my invention; Fig. 3, a vertical section of aportion of the same, taken in the line y 3 Fig. 2.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists, first, in a novel manner of arranging orapplying the supporting-wheels to the training of the machine, wherebythe framing may be readily adjusted higher or lower, as desired.

The invention consists, secondly, in a novel manner of arranging thestandards of the wheels on which the framing is mounted, whereby theaxes of the wheels are rendered capable of being rigidly fixed, so as torotate in planes having a longitudinal position with the framing, orallowed to turn so as to operate like caster-wheels, to facilitate theturning and guiding of the machine while the same is being drawn fromplace to place.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A A represent two inclined side pieces, the upper and front parts ofwhich are connected by cross-bars a a, to which a draftpole, B, isattached. Thefrontcross bar, a, has two pendants, G 0, attached to it,to the lower ends of whichtheplow-beamsD l) are connected byuniversaljoints E E. Thesejoints E E are composed of two metalplates, 1) b, which are bent or twisted so that their outer ends mayabut against the sides of the pendants O G, and be connected thereto bya horizontal bolt, 0, and the inner ends allowed to lap over the upperand lower sides of the beams, so as to be secured thereto by a verticalbolt, (1. By this arrangement the plow-beams are allowed to rise andfall, and also to move laterally at the will of the operator.

F F are the plows, which are attached to standards (1, secured to thebeams in the ordinary way.

G G are two vertical rods, which pass, one through each side piece, A,near its back end. These side pieces rest on shoulders c on the rods,and the side pieces may be adjusted higher or lower on the rods by meansof pins f, by which the shoulders are supported. Each rod G has twobars, H H, attached horizontally to its lower end, and between thesebars the wheels I are fitted.

On the upper part of each rod G there is placed a spiral spring, g, andon these springs the ends of a bar, J rest, the rods G passing looselythrough the bar J. Each rod G has a button, H, upon its upper end,which, in consequence of the springs 9 bearing against the under side ofthe bar J, iit in recesses h in the upper surfaces of said bar. Thesebuttons H prevent the rods G from turning and cause the wheels I torotate in planes parallel with the sides of the framing. This isnecessary when the machine is at work, as itv insures the latter runningin a direct course with the rows of plants.

At the under side of the bar J there are two books, i, to pass intoloops or staples j in the upper surfaces of the beams D D when thelatter are raised. By this means the plows are held in a suspended stateabove the surface of the ground, and the weight of the plows depressesthe bar J, so as to free the buttons from the recesses h and admit ofthe rods G turning, so that the wheels I may operate like caster-wheelsand admit of the machine being guided or turned freely at the ends ofrows or while being drawn from place to place.

Having thus described my invention, what 1 claim as new, and desire tosecure by Letters Patent, is-

The buttons H H, secured to the upper ends of the rods G G, incombination with the bar J, provided with the recesses h h, and thesprings g on the rods G, all arranged substantially as and for thepurpose specified.

CHARLES HOLMAN.
